DIY double-side PCB 2/2 - thru' hole connection and SMD assembly

The workaround of difficult parts of via holes and large parts thru' holes connections in double-side PCB are explained and verified. Wire wrapped is used for them. More strands of wires are needed if the tracks for them will carry larger current. Corresponding holes will need to be made larger as well so wires and pins of component can go thru' it together. During PCB design, the holes dimension should cater for them in advance. Thru' hole wire for component should be soldered away from hole pads on one side first. On the other side, no solder should be put on until component is inserted in it...
